When clouds have a large number of hosts, the default size of the ARP cache is too small. The cache can overflow, which means that the system has no way to reach some ip addresses. Setting the threshold limits higher addresses the situation, in a reasonably safe way (the maximum impact is 5MB or so of additional RAM used). Docs on ARP at http://man7.org/linux/man-pages/man7/arp.7.html, and more discussion of the issue in the bug. Change-Id: I329ec51eff85a2a99a929c67ff0c68b3b36d7273 Closes-Bug: 1780348 |
